Studies on Magnesium Silicates, “Steatite”, Part V

Steps toward interstellar silicate mineralogy V. Thermal evolution of amorphous magnesium silicates and silica

The thermally induced amorphous-to-crystalline transition has been studied for bulk sheets and micrometre-sized particles of magnesium silicate glass (MgSiO3), nanometresized amorphous magnesium silicate (MgSiO3 and Mg2SiO4 smokes) and amorphous silica particles (SiO2). Silicate glass was produced by the shock-quenching of melts. Samples of nanometre-sized smoke particles have been obtained by ...

In situ X-ray di¡raction studies of dense hydrous magnesium silicates at mantle conditions

Lizardite was pressurized up to about 28 and 20 GPa and heated at 1310 ( þ 50) and 1100 ( þ 100)3C; antigorite was pressurized at about 25 and 22 GPa and heated at V10003C, with a Nd:YAG laser using the double-side laser heating technique. Samples were then examined in situ by energy dispersive synchrotron X-ray diffraction. Our results show that phase E, superhydrous phase B, and phase D are i...

Studies on Ringworm. Part V. Fungus Diseases of the Nails and the Surrounding Tissues

This is a report on the investigation of the diseases of the nails and the surrounding tissues caused by fungus infections. The investigation was confined to the isolation and study of the fungi present in the lesions, which are presumably the causative organisms of the diseases of the nails and the tissues immediately surrounding them, causing perionychia. Only those cases were selected in whi...
